Application led December 3, 1921*.'y Serial No. 519,673.

To all 'whom t may concern: n 1

Be it known that we, ALFRED Fnnnnnnc and CARL E. Dorrenowsnr., citizens of the UnitedStates, residing` at Norwich, in the county of New London and State of` (Jonnecticut, have invented certain new and useful Improvements in Selflosiing` Valves, of which the following is a specification.

The present invention relates to self-closing valves constructed so as to be especially useful in fiushing tanks and the like and has for `its principal object to provide a` A still further object of theinv'ention is tov generally improve upon Valves of this character by providingv a-device which will be of extremely simple, durable and inerzpensive con'struction, one which is efficient and reliable in operation, and well adapted y to the purposejfor which it is designed.V

lith these and numerous other objects in view7 the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed," 1

In the drawing YFigure 1 is a vertical longitudinal section taken through the valve, Y

Figure 2 is a transverse section taken on the line 2 2 of Figure 1 looking in the direction of the arrow,

Figure 3 is a transverse section taken on the line 3 3 of Figure 1 looking in the direction vof the arrow.'

Figure 4 is a detailed elevation of the auxiliary valve member,

Figure 5 is a transverse section'taken therethrough on the line'5 5 of Figurent looking'in the direction ofthe arrow, and

Figure' 6 is a similar view taken on the line 6 6 of Figure 4 looking in the direc" tion of the arrow. y

Referring to the drawing` in detail it will beiseen that 1 designates theshell of the vulve which is provided with an inlet chamber 2 preferably having threads therein so that it may be connected to asupply pipe,

a valve chamber 2, and an outlet chamber 3 which is provided with threads so that it nay be connected to a pipe leading to a tank or some other likedevice, when the valve is to be used for flushing purposes.

An opening 4 communicates the chambers v2 and 2 and an opening 5 comprising a valve seat communicates the chambers 2 and 3. In the wall of the shell 1 there is provided a channel 6 which runs longitudinally with the chamber 2 and communicates the-rewith at its top through the aperture 7 and at its bottom through the aperture 8. A screw member 9 is disposed intermediate the ends of the channel 6 so as to extend transversely thereof whereby the flow of water through the channel may be regulated. It is' to be understood that the interior width of the channel is equal to the thickness of the screw. The head of the screw 9 is situated in a boxing- 10 closed by the cap 12. A bon-like valve 13 is movably mounted in the valve chamber 2 and has an opening` 14 in its lower end for movably receiving-the auxiliary valve member 15. Another opening` is provided in its upper end and suitable packing retaining` means 17 is situated therein for supporting' the packing' 18. A rod 19 isL situated transversely of this upper opening across the packing retaininq means 17 so as to limit the movement of the auxiliary valve 15. f

By referring particularly to Figures 4. 5 and 6 it will be seen that the auxiliary valve 15 comprises a disk 16 which is adapted to engagethe valve seat 2O at the upper end of the opening 14, thereby closing theopening 14. A stem 21 depends from the disk16 and has a plurality of grooves 22 therein so as to allow the escape of the water or other liquid when the disk 16 is raised from its seat20.-V

A spindle 23 is j ournalled transversely of the outlet chamber 3 and is provided interg mediate its ends with a cam member y24 adapted to engage the valve stem 21` so as to raise the auxiliary valve 15. `This spindie, however7 is normally held in an inoperative position by the spring 25 which forces the cam constructed end 26 in engagement with the camy block 27 so that kwhen the spindle is turned the spring will be comasy pressed and when the spindle is i this spring and the cam end 2G anu cam block 27 will cause the spindle to return to' its original position.

To operate the valve the spindle 23 is oscillated thereby causing; the cam 2% to engage the. auxiliary Valve l5, that is its stem 2l and lift it from oil the ralye'seat 20L is the spindle is further rotated tl e cam causes the auxiliary Valve l5 to abut the rod 19 and thus litt the box-like valve oil or" its seat 5 and the water is, therefore, allowed to tlow ireely from the inlet chamber 2, through the valve chamber 2, and out through the outlet chamber 3. In the meanwhile the water tlows through the opening 8, through the channel 6, and through the opening 7, to the upper portion ot the valve chamber 2 tending; to lill the box like valve. lllhen the cam 2% of the spindle is disengaged trom the stem of the auxiliary valve this auxiliary valve will close and the water will lill the box-like valve and the portions of the valve chamber thereabout and the weight of the water will become suliicient to overcome the pressure working upwardly on the box-like valve and thus the box-like valve will come to a closed position. The speed at which this box-like valve 13 will close is regulated by the set screw 9 which allows or regulates the water flowing through the channel G.

lllhile. the preferred embodiment ot our valve has been described in detail, it will be understood that we do not wish to be limited to the particular construction set forth, since Various changes in the form, proportions` and ar angement of parts, and in the details et' construction may be resorted to without departing;` from the spirit and scope of the inrentioiu or destroyingy any ol" the advantages contained in the same, heretofore described and defined iu the suhjoined claims.

Having thus described our inyeul ion what we claim as new is: Y

l. A valve comprising` a main body portion, an inlet, an outlet, a channel i'ornied on the side of the body communicating' its upper and lower extremities with the interior of the body, and a valye seat formed adjacent the outlet; a. main Valve slidably mounted in the body comprisinga casing having, a comparatively large opening formed in the upper extremity and a tubular passage formed in the lower extremity thereof, a iianged ring mounted in the upper extremity ot the casing', a rod positioned diametrically across the said ll-ringed ring, a valve seat formed on the upper edge of the tubular passage, packingmeans adapted to permit the main valve to tightly seat upon the seat formed in the main body; an auxiliary vvalve slidably mounted in the tubular passage formed in the main Valve compris ing a i'ali'e stem adapted to snugly the said tubular passage, a dise formed on the upper extremity thereof harinal packing means adapted to engage the seat tormed on the tubular passage, and a rin` on the lower extremity for operating the same; and an operating),- spindle rotatably mount ed in the Valve outlet comprising a cam body mounted centrally ol the outlet and means for readily actuatingthe said can; body.

2. A valve comprising' a main body, an inlet chamber, an outlet chamber, a channel formed on the side of the body,communicating at its upper and lower extremities with the interior ot the body, means for controlling the passage of matter through the said channel, and a main yalre seat formed adjacent the outlet chamber; a main yalre slidably mounted in the body comprising a main casing having a comparatively large opening' formed on the upper extremity and a tubular passage formed on the lower extremity thereof, a flanged ring mounted on the upper extremity of the casing, a rod mounted diametrically across the flanged ring, an auxiliary valve seat yformed on the upper edge of the tubular passage, and means ii'or tightly )fitting` the said main valve upon the main valve sea-t; an auxiliary valve adapted to engage the seat termed on the tubular passage; and a ring formed on the lower extremity ol the valve by which the same is actuated; and operating),` means consisting,` of a cross shaped cam member positioned transversely across the outlet chamber` a stem for rotating the same and raising' the auxiliary and main Valve members in the order named.
